Lazada complaint: Unhelpful and rude customer support, lying supervisors, a manager who promised to call but wouldn’t

I’m a customer of Lazada. This 9.9 sale alone, I’ve spent about 14,000 pesos to buy some of their listed products. I had a big problem with one particular seller. After several days of not shipping my order and after the sale is already over, I asked why my order is not being shipped and they told me that the item was not available and I told them that they could’ve told me earlier so I could’ve bought something else from other sellers while it was still on sale. The seller is very unhelpful and wouldn’t refund right away. I contacted Lazada customer support and talked to several representatives. I was then passed to supervisor Sally (Salvacion) who then called me and promised that the refund will be processed within the day and that she will issue a voucher of 800 pesos. She only issued a voucher of 500.

I contacted customer support again the next day trying to rectify the issue. At this point, the 9.9 was extended and I saw an item that I want from another seller and thought I could get it with the refunded money and correct voucher amount. Sally kept promising that it will be refunded today and that she can correct the voucher amount but yet again, nothing happened. I even contacted the seller numerous times to have them cooperate with Lazada. I was not getting help at all from anyone.

One representative in particular, dropped the chat and refused to help me when I asked to speak to a supervisor. One supervisor, Maricar, also promised me that the manager will call me but nothing came. The extended sale passed and I was locked out of the discount. At this point, my chat requests are not being handled as it looks like they’ve blocked me from contacting customer support.

I’m now seeking legal advise on how to handle the issue further.
